Abstract: Latent hardening aqueous polyurethane dispersions contain (1) a disperse phase (P.1) containing (1a) a polyurethane (PUR.1a) containing groups (G-1) imparting dispersibility in water and groups (G-2) with a carbon-carbon (C-C) double bond activated by a carbonyl group bound directly to this or (1b) a mixture of a polyurethane (PUR.1b) containing G-1 groups but not G-2 groups and a compound (I) containing G-2 groups, other than PUR.1a and PUR.1b; and (2) a compound (II) which contains an average of NOTLESS 2 hydrogen (H) atoms as amino function, has a water solubility > 1 g/l (25 degrees C) and has a number average molecular weight (Mn) of 200-1000000. Also claimed are wood, metal, textile, leather or plastics articles bonded, impregnated or coated with the dispersions.
